what is distance time graph what is the nature of the distance time graph of a body in the following cases represent graphically
Answers
Answer:
Distance-time graph:
It is a graph obtained by plotting distance travelled along Y-axis and time taken along X-axis.
(i) Distance-time graph for stationary body:
The position of a stationary body does not change with time. So distance-time graph for a stationary body is a straight line parallel to time axis, as shown in Fig. 8.7 (a).
(ii) Distance-time graph for uniform velocity:
For a body moving with uniform velocity, the distance travelled is proportional to the time taken. So distance-time graph is a straight line inclined to the time axis, as shown in Fig. 8.7 (b).
(iii) Distance-time graph for variable velocity:
When a body moves with variable velocity, it covers unequal distances in equal intervals of time. So the distance-time graph is not a straight line but it is a curve, as shown in Fig. 8.7 (c).
